works in decaying birch and it is probable that the larvae are somewhat

Grynocharis quadri-lineatus Melsh. 

 This black, rather flattened beetle occurs on beech stumps in May. 

 The eyes are medium, rather finely granulated ; head somewhat coarsely, 

 and prothora.x rather finely punctured, while the wing covers are marked by 

 a number of conspicuous ridges with the interspaces coarsely punctured, 

 almost reticulate. 



Xylocleptes species 

 Dark brown or black beetles, about 'A,., inrh long, make longitudinal burrows in 

 partly decayed sugar maple limbs. 



This species was met with by the writer in very small niunbers August, 

 1901 at Axton N. Y., in a dead sugar maple limb. The adult beetles run a 

 somewhat tortuous longitudinal gallery just under the 

 bark and escape, as in the case of most bark borers, 

 through round holes about ' (,4 inch in diameter. A 

 central chamber was detected in one instance and in this 

 case there were two longitudinal galleries proceeding 

 therefrom and slight notches indicated the beginning of 

 two others. Eggs are evidently deposited on either side 

 of the burrow and the young makes somewhat tortuous 

 galleries at approximately right angles to those of the adults. The insects 

 were probably breed- ^l|^^||mf| ' f 

 ing at the time they 



were collected, as a Fig. 113 XylocUptes work m decaying m.iple twig (original) 



few larvae were seen but not preserved. 



Description. The beetle is less than 3 33 inch in length, cylindric, rather 

 slender and of a dark brown coU)r except the legs, which are a light brown. 

 The head is well retracted and the black eyes are coarsely granulate. The 

 anterior portion of the prothorax is tuberculate, the dorsal part and the 

 wing covers or elvtra are rather sparsely and coarsely punctured.
